The Display transmitter series is a kind of DC analog signal or digital signal device which changes the power and non-power parameters in the power grid into linear. It can be connected with a microcomputer through the RS485 serial interface to form a measurement and control system. The internal use of switching power supply, the auxiliary power supply requirements are low (power supply AC, DC General), the series has a strong anti-jamming performance, its anti-jamming performance in line with IEC electromagnetic compatibility level 3 provisions, other in line with GB/t 13978-92 provisions, the series is applicable to machinery, telecommunications, electricity, petroleum, chemical, steel , Sewage treatment, building construction, power plants, substations and other modern power supply and distribution systems, a high-performance intelligent transmitter.

KDY-40N Neutral-line power surge protector is a neutral point-to-ground over-voltage protection device for power voltage transformers. It is designed and manufactured according to IEC and other relevant lightning protection standards, has no freewheeling, low residual voltage, and steep wave It has the advantages of rapid response, small discharge dispersion, and the ability to absorb various lightning and operating overvoltages.

The flow capacity of the KEJIA KDY-I-25S power supply lightning arrester is large, and it is a switch type first class lightning protection protector. The lightning arrester has no leakage flow and no continuous flow. The performance is reliable and the work is stable. According to the principle of lightning protection, the power line still has high residual pressure after the lightning energy is released once, and the lightning energy should be released step by step through the rear lightning protection device of the lightning protection system so as to effectively protect the terminal electric equipment.
